COMBINED WHEELED SCRAPER AND DUMPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 710,592, dated October '7, 1902.

Application filed January 20,1902- Serial O- 90.510. (N0 model.)

T 0 (0Z7, whmn it may concern.-

Be it known that I, MARvIN MEAD, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Combined lVheeled Scraper and Dumping Device, of which the following is a specification.

This invention relates generally to wheelscrapers, and more particularly to a combined scraping and dumping device.

The object of the invention is to provide a device embodying these characteristics which shall be exceedingly strong and durable and highly efficient in operation.

Another object of the invention is to provide a device in which the draft is placed upon the scraper or scoop during the scraping operation, thereby relieving the supportingframe from strain.

Another object of the invention is to provide a scraper or scoop which dumps rearwardly, thereby avoiding the reversal or turning upside down of the scraper or scoop.

With these objects in View the invention consists, essentially, in suspending a scraper or scoop from a horizontal axle, said suspension device being adjustable, whereby the scraper or scoop can be raised or lowered, as desired, said scraper or scoop being dumped by tilting the axle rearwardly, thereby elevating the forward end of the scraper or scoop, and simultaneously opening the tail-gate of the said scraper or scoop,permittingit to dump rearwardly.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure l is a perspective view of a wheel-scraper constructed in accordance with my invention, the scoop or scraper being elevated above the ground. Fig. 2 is a view taken from one side, one of the wheels being removed, the scraper or scoop being shown arranged above the ground in full lines, the position of the parts during the dumping operation being indicated in dotted lines, the spokes of the wheel being omitted in order to more clearly illustrate the position of the several parts. Fig. 3 is a detail perspective view illustrating the manner of securing the bars of the frame to the axle. Fig. 4c is a side view of the device, one of the wheels being removed, the scoop being shown lowered into position for scraping or scooping up the earth. Fig. 5 is a top plan view of the device, the parts being shown in the same position as illustrated in Fig. 4:.

It will of course be understood that the device can be made any size desired, according to the work to be done, and that the various parts can be made of any material suitable and convenient for the purpose it is intended to serve.

In the construction of my scraper I employ an axle A, which is preferably square in crosssection and has the ground-wheels B mounted upon its opposite ends. Parallel bars 0 and the oblique brace-bars D are rigidly connected at their rear ends to the axle A, the forward ends of the said parallel bars 0 and brace-bars I) being connected to each other; but it will be understood that the forward ends of the parallel bars O are not connected to each other, each bar being connected to the adjacent brace-bar. The rear ends of the bars C are preferably bent back upon themselves, providing elongated loops O, through which the bolts 0 pass, the threaded ends of said-bolts passing through plates 0 arranged upon the bottom of the axle and secured by suitable nuts, said bolts and plate securely fastening the bar O upon the upper face of the axle. Each brace-barD is formed with a similar loop D at its rear end, through which the bolts D are passed, said bolts passing through a plate D secured upon the bottom of the axle. A clip D is arranged upon the outer side of each loop D, said clip being connected to the plate D arranged upon the bottom ofthe axle, and the plates D and D are each formed with a bearing D upon its forwardend. Theinnerendsof thelever-arrnsE are pivoted between these bearings D, a pivotbolt E passing through said bearings and also through the end of each lever-arm E, said leverarms bei ng bent toward each other and secured at E to an operating-handle E Each leverarm E is formed with a bend or elbow E adjacent to its inner or pivotal end, and connected to each lever at this bend or loop is a suspending strap or bail F, said bail or strap being rigidly secured to the scoop G, upon the exterior thereof. Ears or lugs G are secured on the outer side of each end of the scoop orscraper, and pivotally connected to each ear or lug is a metallic strap or plate H, said plate or strap being rigidly connected to the adjacent end of a draft bar or beam 1, said beam having a clevis I connected to the center of the same and carrying the doubletree 1 the ends of said doubletree being provided with singletrees 1 The tongue or pole K rests between the parallel bars 0 and is pivotally connected to said bars about midway their length by means of a bolt K, passing horizontally through the said bars and tongue or pole. The rear portion of the tongue or pole rests upon the axle A, the rear end projecting a short distance beyond the said axle, as most clearly illustrated in Figs. 2 and 4. The tongue or pole is not connected to the axle or frame in any other manner. A chain K is passed around the tongue or pole and supports the doubletree in its proper position, said chain preferably passing through the clevis I. The scraper is provided with upwardly-projecting ears G ,to which the tailgate G is pivoted, said tail-gate being provided with inwardly-projecting wings, which are connected to the said ears G A hook G is attached to the upper edge of the tail-gate at its center, and connected to said hook is a chain L, the upper end of which is connected to a hook or plate L, secured upon the rear end of the tongue or pole K. Rearwardly. and upwardly projecting handles G5 are also attached to the ends of the scoop. In Figs. 1 and 2 I have shown the scraper or scoop elevated above the ground, and this is the position it would occupy during transportation, either loaded or unloaded. It will be noted that the lever-arms E are thrown rearwardly and forced down until they meet and rest upon the axle A. This brings the pivot-point between the bails F and lever E to a substantially central position, thereby throwing the weight of the scraper or scoop loaded or unloaded upon the axle. The draftbeam is also held in its proper position.

When it is desired to scrape or scoop the earth, the lever-arms E are thrown forwardly, the handle E resting upon the tongue or pole, as most clearly shown in Figs. 4 and 5. This forward movement of the lever-arms lowers the scoop, so that its forward edge will contact with the ground and scoop or scrape off a definite amount thereof. The draft will be applied directly to the front end of the scoop, thereby relieving the supporting-frame of all strain. After the scoop has been filled the lever-arms are thrown back to the position indicated in Figs. 1 and 2, and the loaded scoop is then ready for transportation. lVhen it is desired to dump the scoop, the axleA is rocked by means of a hand-lever M, rigidly connected thereto, said rearward rocking movement of the axle serving to tilt the scraper or scoop upwardly at its forward end and downwardly at its rear end, and inasmuch as the tongue or pole is pivoted between the parallel bars 0 said tongue or pole will remain substantially horizontal, but will be slightly elevated, owing to the fact that the parallel bars (3 are elevated or inclined by the rocking movement of the axle. This upward movement of the tongue or pole causes an upward pull upon the chain L, thereby completely opening the tail-gate at the rear end of the scoop simultaneously with the lowering of the rear end and the raising of the forward end, thereby completely and quickly dumping the scraper or scoop. After the dumping operation has been effected the parts are permitted to assume their normal' positions, and the empty scoop can then be wheeled back to its place of operation.

It will thus be seen that I provide an exceedingly strong and durable wheel scraper or scoop, and one which on account of its simplicity of parts can be quickly and easily loaded and unloaded.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. In a wheeled scraper, the combination with the axle, of the frame connected thereto, the lever arms pivotally connected to the axle, the scraperorscoop suspended from said lever-arms, the pole or tongue pivotally connected to the frame, means for rocking the axle and a connection between the rear end of the tongue or pole and the tail-gate of the scraper or scoop, substantially as described.
